Window in poured concrete wall

[jar546]

Educational:

Sloped lot, 1st floor at grade at the front and walk out basement in the back. They plan on finishing the basement. The foundation will be 8" poured concrete. The rear of the planned residence is walk out basement and they are planning on having 2 windows framed for the pour in addition to the planned 6' slider. 90 mph wind zone and seismic zone B.

What is the minimum steel reinforcement required around the window openings per the IRC 2009 if the windows will have a rough opening of 32w x 48"h?

1 story with roof.

See section 611.8.1.1 & 611.8.1.2

Still no definitive answer other than where to go to find the answer.

minimum of one #4 within 12" of opening if greater than 2 feet .... 6.11.8.1.1

and a Lintel - see 611.8.2 and the limitations of the appropriate table starting at R 611.8(1)

In essence, not enough information is given as far as clear spans, or building width, depth etc.

So what do you do when they want to finish the basement and need to cut the wall for the window?
